(57) Abstract:
(EN): A system comprises a tag (21) being associated with a user (22), a display apparatus (4) for displaying an image, a receiver (31) which receives a tag signal (27) from the tag (21) to supply a received signal (RS), a detector (32) which receives the received signal (RS) to supply a detect signal (DS) which has an active status when the tag (21) is present in a first area (Al) closer to the display apparatus (4) than a predetermined distance (Dl), the detect signal (DS) having an inactive status otherwise, and feedback means (33; 42, 43, 44; 35, 45, 43) which receives the detect signal (DS) to provide an user detectable feedback (FB) which indicates to the user when the detect signal (DS) changes to or has the active status.
